+**Codebase scan and ship-time capability hooks now honor your model settings** — /gsd:scan dispatched its mapper agent with a model placeholder nothing resolved, and ship-time capability hooks did the same, so `model_overrides` and `model_policy` were silently ignored at both and the agent ran on whatever the session happened to be using. Both now resolve a real model, and omit the model parameter entirely when it resolves to "inherit" or empty rather than passing an empty value that fails on non-Claude runtimes. Note: the scan mapper now runs on the model your profile selects rather than inheriting the session's. (#2684)

 # Model Profile Resolution
 
-Resolve model profile once at the start of orchestration, then use it for all Task spawns.
+Resolve each agent's model through `gsd-tools`, then pass it to the `Agent()` spawn — or
+omit the parameter entirely when nothing resolved.
 
 ## Resolution Pattern
 
-```bash
-MODEL_PROFILE=$(cat .planning/config.json 2>/dev/null | grep -o '"model_profile"[[:space:]]*:[[:space:]]*"[^"]*"' | grep -o '"[^"]*"$' | tr -d '"' || echo "balanced")
+Prefer the field your workflow's own `init.*` payload already emits (every orchestrator
+init that spawns subagents carries one — `mapper_model`, `planner_model`,
+`executor_model`, `doc_writer_model`, …). Declare it in the workflow's parse line so the
+binding is stated, not implied:
+
+```
+Parse JSON for: `mapper_model`, …
 ```
 
-Default: `balanced` if not set or config missing.
+When the agent type is only known at runtime — a capability hook naming its own agent, for
+example — resolve it directly instead:
+
+```bash
+AGENT_MODEL=$(gsd_run query resolve-model "<agent-type>" --raw)
+```
+
+Both surfaces return the same thing: a model string for the active runtime, or the **empty
+string** when nothing resolved.
 
 ## Lookup Table
 
 @~/.claude/gsd-core/references/model-profiles.md
 
-Look up the agent in the table for the resolved profile. Pass the model parameter to Task calls:
+## Passing the model to a spawn
 
 ```
-Task(
+Agent(
   prompt="...",
   subagent_type="gsd-planner",
-  model="{resolved_model}"  # "inherit", "sonnet", or "haiku"
+  model="{planner_model}"
 )
 ```
 
-**Note:** Opus-tier agents resolve to `"inherit"` (not `"opus"`). This causes the agent to use the parent session's model, avoiding conflicts with organization policies that may block specific opus versions.
+Substitute the field **this workflow bound** — never a generic placeholder name.
 
-If `model_profile` is `"adaptive"`, agents resolve to role-based assignments (opus/sonnet/haiku based on agent type).
+**#2517 — omit, do not emit an empty model.** When the resolved value is `"inherit"` or
+empty, **omit the `model=` parameter entirely**:
 
-If `model_profile` is `"inherit"`, all agents resolve to `"inherit"` (useful for OpenCode `/model`).
+```
+Agent(
+  prompt="...",
+  subagent_type="gsd-planner"
+)
+```
+
+No model parameter is passed at all — `planner_model` resolved to `"inherit"` or empty, and
+omitting it inherits the orchestrator's model. Passing either value through as an argument
+instead 404s on non-Claude runtimes.
+
+This is not cosmetic, and both values really occur. `model_profile: "inherit"` — and any
+opus-tier agent — resolves to the literal string `"inherit"`. `resolve_model_ids: "omit"`
+resolves to the **empty string** whenever the project sets it explicitly or the active
+runtime has no native tier aliases; an agent type absent from the profile table takes that
+same empty-string path, because it has no tier for the earlier steps to resolve. Emitting
+either value verbatim fails the spawn on every runtime without native tier aliases.
+
+**#2684 — substitute a field your workflow actually bound.** `model="{…}"` must name a key
+your own `init.*` payload emits, a shell variable you assigned, or a field on your declared
+parse line. A placeholder that resolves to nothing does not fail loudly — the orchestrator
+silently invents a value, which is the invisible partial application ADR-1411 prohibits.
+`tests/model-omit-when-inherit-guard.test.cjs` enforces both rules.
+
+## Profile semantics
+
+**Note:** Opus-tier agents resolve to `"inherit"` (not `"opus"`). This causes the agent to
+use the parent session's model, avoiding conflicts with organization policies that may
+block specific opus versions — and, per the rule above, means the `model=` parameter is
+omitted rather than set.
+
+If `model_profile` is `"adaptive"`, agents resolve to role-based assignments (opus/sonnet/
+haiku based on agent type).
+
+If `model_profile` is `"inherit"`, all agents resolve to `"inherit"` (useful for OpenCode
+`/model`).
 
 ## Usage
 
-1. Resolve once at orchestration start
-2. Store the profile value
-3. Look up each agent's model from the table when spawning
-4. Pass model parameter to each Task call (values: `"inherit"`, `"sonnet"`, `"haiku"`)
+1. Bind the model once — from the `init.*` payload field, or `query resolve-model` when the
+   agent type is runtime-determined
+2. Declare the bound field on the workflow's parse line
+3. Pass `model="{bound_field}"` on each `Agent()` spawn
+4. Omit `model=` entirely whenever the bound value is `"inherit"` or empty

+  **#2684 model resolution.** `init.phase-op` emits no model field, and `ref.agent` is only known at runtime, so resolve it per hook before dispatching.
+
+  **Input validation (defense-in-depth) — do this IN-CONTEXT, before any shell use.** `ref.agent` originates in a capability manifest, which may be third-party. Check the value you read from `activeHooks` against `^[A-Za-z0-9][A-Za-z0-9._-]*$` yourself, the same way you read `activeHooks` itself — **never** by pasting it into a shell command to be tested there. A value carrying a quote, `;`, `` ` ``, `$(`, or a newline would terminate the assignment and run as its own statement *before* any shell-side check could execute, so a shell-side check is no protection at all.
+
+  A value that fails the check is a malformed manifest: record a warning, **skip that hook entirely**, and move to the next `activeHooks` entry. Do not dispatch it and do not place it in a command line.
+
+  Only once the value has passed, resolve its model — substituting the validated value for `<agent>`:
+
+  ```bash
+  HOOK_AGENT_MODEL=$(gsd_run query resolve-model "<agent>" --raw 2>/dev/null || true)
+  ```
+
+  **#2517: omit the `model=` parameter entirely when `HOOK_AGENT_MODEL` is `inherit` or empty** — a capability may name an agent absent from the model-profile table, which resolves to the empty string, and passing an empty model 404s on non-Claude runtimes. Omitting inherits the orchestrator's model.
+
+  With a resolved model (`{HOOK_AGENT_MODEL}` is the value the command above printed; `${…}` are bound shell variables):
+
+  `Agent(subagent_type=ref.agent, prompt="Ship-time capability hook for phase ${PHASE_NUMBER}. Phase dir: ${PHASE_DIR}. Consume: ${consumed_files}. Follow your agent instructions.", model="{HOOK_AGENT_MODEL}")`
+
+  When it resolved to `inherit` or empty, drop the parameter:
+
+  `Agent(subagent_type=ref.agent, prompt="Ship-time capability hook for phase ${PHASE_NUMBER}. Phase dir: ${PHASE_DIR}. Consume: ${consumed_files}. Follow your agent instructions.")`
 - If `ref.skill` is set, dispatch with `Skill(skill="gsd-${ref.skill}", args="${PHASE_NUMBER} --auto ${GSD_WS}")` (prepend `gsd-` to `ref.skill`).
 
 Each dispatch is best-effort: if it errors, record a warning and continue — never re-raise (`onError: skip`).
